A sketch and a caption want different things from a page. The sketch wants room with nothing printed on it to compete for attention. The caption wants a line to sit on so it does not drift. This ruling gives each its own field on the same page instead of making one of them lose.

The ruled strip runs at college pitch, 7.14 mm, the same rule used elsewhere on this shelf. It is there for a label, a measurement, a date, or a few lines explaining what the sketch is meant to show a reader who was not in the room when it was drawn.

The split does not decide how much of the page belongs to which half. That is still a decision made by hand, page by page, the way it always was on plain paper.

The film

Page by page

A vertical film from our own bench — this page contacts nobody's server to play it, and downloads nothing until you press play.

A vertical film, 27 seconds: the ruling page and the figures printed on its last leaf. Synthesised ambient bed, no dialogue — captions in three languages.

Real pages

A close view of the upper, unruled half of a page, with the first horizontal rules beginning below it.
The break between the blank half and the ruled half.
The front matter page, stating the contents and their pages, the ruling and the signature count, then a short checklist.
One page, two jobs: draw above, write below.
The pen-test leaf, with pen, ink and swatch columns and the printed figures: sketch-rule, 7.1 mm, 21 rows per page, one column.
The row count is for the ruled half.

Questions

How is the page divided?

A plain field for drawing and a ruled strip at college pitch, 7.14 mm, for a caption or note.

Does the ruling fix the proportion between sketch and note?

No. How much of the page goes to each is decided by hand, not printed in.

What is the ruled strip good for besides a caption?

A measurement, a date, or a few lines explaining what the sketch shows.

Is it dated?

No.

Does it come with a cover?

No. It is the sewn block, sized for a leather cover made separately.
